UNITED STATES PATENT QEErOE.

THOMAS E. MCDONALD, OF TRENTONNEW JERSEY.

Specification forming part of Letters Patent No. 119,235, datedSeptember 26, 1871.

To all whom 'it may concern:

Be it known that I, TI-rOMAs E. MODONALD, of Trenton, in the countyoflVlercer in the State of New Jersey, have made. certain Improvementsin Spindles for Glotlies-Wringer Rolls, of which the following is aspeeilication:

The object of this invention is to produce an improved spindle forclOthes-wringer rolls; and

Vit consists in the construction of the spindle, as

is more fully hereinafter set forth.

In the drawing, 4ligure l is a longitudinal sectional view of thespindle. p Fig. 2 is a side view oi same. Fig. 3 is a transversesectional view at y y of Fig. 1. Fig. 4 is a longitudinal sectionalview, and Fig. 5 is a transverse sectional View at z z of Fig. 4, andare modifications of Figs. 1, 2, and 3.

A Al represent the journals of the spindles, made from round metal bars,of the proper size and length. B B are metal bars, convex On their outerand concave on their inner sides to t upon the metal forming thejournals, of the proper width and thickness, and of the length to lapupon and be Welded or brazed to Opposite sides of each Of the journalsA, but not wide enough to surround the journals, but leave a space ofonesixth, more Or less, of the inner diameter of said bars between themand on each Opposite side of the journals A. Gis a center bar or rod oi'metal, of round iron or other metal7 of about One-half the diameter ofthe journals, and is inserted and fastened into the inner ends of thejournals at their centers, as seen in Fig. 1, by boring Or otherwisemaking a hole of the proper size to receive and hold it and leave aspace, a., around and between it and the bars B 5 or, instead of thecenter bar G being made of round metal,

it may be made of a liat bar, and project a little outside of thediameter of bars B on their convex sides, as seen in Figs. fl and 5, asthis form would give the center bar G a hold of the rubber Outside Ofthe diameter of bars B, and their hold of the rubber forming the roll,thus acting upon more of the material ofthe roll than if made with theround center.

'The spindle may be of east malleable iron, ii' preferred. Any knownmethod of attaching the rubber iirmly to the spindle when thus formedmay be adopted, as the manner of attaching the rubb'e'r to the spindleis no part of this invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The clothes-wringer rOllspindle above de` scribed, consisting oi' thejournals A, metal bars B, and center bar C, united to the journals A,and leaving the open space a, in the manner and for the purpose setforth.
